The SOUTHWIRE 175 is a 2-inch snap-on conduit bushing designed to protect wire and cable insulation at conduit entry and exit points. This type of bushing snaps onto the end of conduit or a knockout opening without requiring threading, making installation faster in panel, enclosure, and junction box applications. Licensed electricians and electrical contractors install this fitting during rough-in and finish work wherever conduit terminates and wire protection is required. The snap-on design eliminates the need for tools during seating, reducing labor time on repetitive conduit terminations.
This bushing is suited for use in residential and light commercial electrical installations. It is commonly installed at the knockouts of load centers, sub-panels, enclosures, and electrical boxes where 2-inch conduit is present. The part is also cross-referenced under Madison 175 and Topaz SB2.531, making it a direct drop-in option for jobs calling out either of those part numbers.
Compatible with 2-inch conduit terminations and knockout openings. Cross-referenced as a direct replacement for Madison 175 and Topaz SB2.531. Designed for use in standard residential and light commercial electrical enclosures and panel applications.
Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the panel or enclosure before working at any conduit termination point. Seat the bushing firmly onto the conduit end or knockout edge until it snaps into place and is fully captured. Inspect the bushing seating before pulling wire to confirm the protective edge is fully engaged.
